Be it known that L'JOHN G. CUNNINGHAM, a citizen of the United States,residing at Bellavista, county of Shasta, State of .Cali fornia, haveinvented an Improvement in Cream and Butter Separators; and I herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to improvements in devices for separating creamfrom milk and for separating butter from cream of the type employing arotary dash and in which air is injected into the liquid during theprocess of agitation.

It consists of the parts and the constructions and combinations of partshereinafter described and claimed.

Figure 1 is a vertical central section of my device. Fig. 2 is ahorizontal section on lines to at, Fig. 1. Fig. 3 is an enlargedsectional View of the shaft-head and means of fitting it to the dasher.

A represents a suitable base mounted upon the legs or standards 2,fitting in sockets 3 on the base. The receptacle 4, in which the liquidto be treated is contained, rests on a resilient packing 5, as rubber,upon the base. The bottom of the receptacle is centrally perforated,andan annular flange orsleeve 6, integral with the receptacle, surroundsthe perforation and extends downwardly through and beneath the base orsupport. A bracket 7 is secured to the under side of the support, and inthis bracket is journaled a vertical shaft 8, which extends up throughthe sleeve into the receptacle, and its upper end is provided with anenlarged head 9. The bracket has a portion 10 fitting snug up into thesleeve. An annular flange 11 on the upper side of the bottom of thereceptacle surrounds the shaft. The top of the portion 10 extends nearlyflush with the flange 11, and it is bored out to form a stuffing-box inwhich a suitable packing12 is placed. A bushing 12 screws into thestuffing-box and compresses the packing to form a tight joint, being adjustable as the packing wears. The head 9 of the shaft bears upon the endof the bracketpiece 10. This offers the sole support for the shaft,which is held tightly to its seat by means of the horizontal fly orbalance wheel 13, secured to the-lower end of the shaft below thebracket. The portion 10 has a ledge against which the shoulder 14 of theflange 11 is adapted to bear. The lower end of the sleeve G is threaded,as is likewise the corresponding portion of the bracket, and the partsare drawn together by means of a union 15. This effects a tight jointand causes the receptacle to be secured firmly on the base, making itperfectly rigid and free from vibration.

Power to rotate the shaft 8 is transmitted through the horizontal shaft16 and bevelgearing 17. Upon the upper end of the shaft 8 is mounted arotary dasher, which consists of a hollow stem 18,havingflanges 19 nearits lower end, in which the radial blades or paddles 20 are secured. Thelower end of the stem has a socket 21, in which are the keys 22, fittingvertical slots in the head 9 of the shaft, whereby the parts are lockedtogether and made to revolve in unison.

The receptacle is provided with a cover 23 and opening 24:, throughwhich airis admitted to the open-ended stem and thence passes downwardlyinto the body of liquid through the perforations 25 between the arms.The flange 11 on the bottom of the receptacle has one or moreprojections or keys 26, adapted to fitcorresponding keyways in a ring27,

which slips over the flange and rests on the bottom of the receptacle.Extending radially from this ring are arms 28, on the outer ends ofwhich are supported the vertical perforated brake bars or arresters 29.The object of these bars or baffles is to increase the agitation of theliquid set in motion by means of the rotary dasher. The latter, inaddition to the arms 20, has two lateral perforated flanges 30,extending to near the upper end for the purpose of further increasingthe agitation, and thereby expediting the separation of the particles.

In order to maintain the liquid in the separator at an equabletemperature, I surround it with a water-jacket 31, leaving a space 32unjacketed 011 one side for a draw-0d cook 33 and gage-glass 34. Thejacket may be filled through a funnel portion 35. While I could be madedetachable, so that the separator could be used alone, if desired.

The shaft-head 9 is practically of the same diameter as the interiordiameter of the sleeve 6, so that the parts can readily be removed atany time for cleansing or for other purposes.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- 1. The combination in a separator, of acontaining-receptacle, having a central perforation and an annularflange or sleeve surrounding the same; a stem supported centrally in thereceptacle said stem made hollow throughout its length and open at bothends, and provided with perforations near the lower end; a shaftextending in line with the stem and having, at its upper end, anenlarged head said head adapted to fit a corresponding socket in theunder side of the stem; a supportingbracket having a tubular portionsurrounding the shaft and provided with a stufliug-box, said enlargedhead bearing upon the end of the tubular portion of the bracket; meansfor rotating the shaft; radial arms carried by the stem; a ring fittedto the central sleeve orannular flange on the bottom of the receptacle,and having radial horizontal arms the outer ends of which standvertically and are provided with perforations.

2. An improved cream and butter separator consisting of. a support orbase including a bracket having a tubular portion 10 provided atitsupper end with a stuffing-box, and having a shoulder 14:; a receptaclehaving a central opening in its bottom and having a sleeve 6 and anannular flange adapted to rest upon said shoulder; means detachahlycoupling the said sleeve to the bracket; a vertical shaft extendingthrough the tubular portion of the bracket and having, at its upper end,an enlarged head adapted to rest upon the top of the said tubularportion; a vertical hollow stem open at both ends; flanges on the lowerpart of the stem and radial blades fixed between said flanges, said stemhaving perforations between said blades; means for rotating the shaft,and vertically-disposed, perforated baffles on the stem and also fixedto the receptacle.

In Witness whereof I have hereunto set my hand.
